Definitions

  • Trick mode operations are traditionally thought to include forward and reverse playback modes for video, among other operations.
  • fast forward and fast reverse operations for video playback control as well as their slow motion counterparts are implemented on the basis of time. That is, whether in a forward direction or a reverse direction, a fast playback is performed at some integer multiple of the normal playing speed, where the magnitude of the exemplary integer multiplier is greater than one (1).
  • slow motion replay is performed by using a multiplier with a magnitude that is less than one and greater than zero.
  • the sign of the multiplier is utilized to determine the direction of the operation, where a positive sign will usually designate a forward operation while a negative sign will usually designate a reverse operation.
  • the frame rate multiplier L is determined at steps 2 and 3 from a trick mode command received by the video display or presentation device such as a set top box combined with a television.
  • a trick mode command is generally received from a remote control device as a fast forward or reverse command.
  • the trick mode command includes the frame rate multiplier, L, and an indicia of a direction of replay (i.e., forward or reverse) in the trick mode. Since trick modes operate at frame rates that are less than or greater than the normal frame rate, M, it is assumed that the frame rate multiplier L is not equal to 1.
  • the indicia of direction is formulated as a sign, wherein a positive value of L indicates the forward trick mode at L times the normal frame rate and a negative value of L indicates the reverse trick mode also at L times the normal frame rate.
  • each semantic interval Tj that is replayed in a trick mode has a sufficient number of frames to span the full replay period of T/(LxN) seconds. This can be accomplished by comparing the magnitude of the calculated trick mode frame rate Vj for a semantic period Tj to a threshold rate.
  • a threshold rate is the normal frame rate, M. If the magnitude of V; is less than M, then the calculated trick mode frame rate is replaced by a new value and set to the normal frame rate M. The magnitude of the calculated frame rate is used to compensate for the fact that forward and reverse frame rates have positive and negatives signs, respectively.
  • trick mode operation even though some portions of the video content may be played at the normal speed in trick mode, it can be desirable to mute the audio associated with the displayed video content in the semantic interval to maintain consistency and a pleasant viewing experience.
